The logs were sawn at the scragg headrig that produced a two-sided cant, slabs and sawdust.

The overrun and underrun was based on the cant and lumber volume for each log group in the yield study.

The results indicate that, compared to straight sawing, curve sawing 6- and 8-inch two-sided cants does not significantly improve lumber yield from small-diameter hardwood logs with average sweep scale deductions of approximately 5 percent and an average of 1.

The results of this study reveal that, compared to straight sawing, curve sawing cants from logs has no effect on total pallet part yields.

The results of this study indicate that, compared to straight sawing, there is no significant change in average lumber length due to curve sawing cants from logs with less than 30 percent sweep scale deduction, or average sweep ranging from 0 to 3.

Since cants have variable trim allowances and are always purchased by length to the next lowest foot, kerf loss due to cutting cants to part length is negligible.

Some mills ripped cants into multiple part thicknesses.

In all, 2,016 hardwood cants totaling 47,258 BF were graded during these studies.

All cants were classified based on the total defect percentage and the results are presented in Figures 7 and 8.

Ninety percent of the cants studied were found to have less than 10 percent of total unsound volume, and only 2 percent of the cants had more than 30 percent unsound volume.

This study suggests that cants can be pre-sorted for sales to pallet producers with some even culled in the sawmill processing.

The transverse vibration technique was used to estimate the MOE of boards obtained from octagonal cants, using a Metriguard Model 340 E-computer.

Stress-wave speed measured in Douglas-fir cants increased 2 to 19.
